What madness it is for a man to starve himself to enrich his heir, and so turn a friend into an enemy! For his joy at your death will be proportioned to what you leave him.
Seneca the YoungerThere is nothing that we can properly call our own but our time, and yet everybody fools us out of it who has a mind to do it. If a man borrows a paltry sum of money, there must needs be bonds and securities, and every common civility is presently charged upon account. But he who has my time thinks he owes me nothing for it, though it be a debt that gratitude itself can never repay.
Seneca the Younger
